It is essential that the software does not get mixed up with your normal copy of Frameit.
If possible use another computer, if not make sure that you use a directory completely separate from your normal Frameit.
Create a Directory or Folder and call it GST. The files I supply will, by default, unzip to a directory called C:\GST (you can change if this does not suit you).
Copy your existing Frameit to the new directory (C:\GST)
Click on Hyperlink below and unzip it into C:\GST on top of
the copy of your data.
Start the system and you should be up and running with your old data.
Go to Maintenance then Program Options. After the TAX types you will see and entry called GST. Select this entry.
Welcome to GST
What you may find interesting is to have both systems running at the same time. So on your normal Frameit do a job and on the GST Frameit, do the same job. Compare the prices.
